' STUFFING-BOX.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed February 2, 1906. Serial-N0. 299,070.

The object of this invention is to provide a very simple and eflicient stuffing box for engines,one that will not require constant repacking and 'will remain cool under all conditions.

My stuffing box is speciall well adapted for an engine having a pair 0 tandem cylinders. It allows the engine to be made very compact, for it is unnecessary to rovidespacefor continued access to the stu ng box. Atv

the same time my stuffing box may be very conveniently removed when desired. In explosive engines, my stufling box is water cooled by the circulating water from one of the cylinders. My mechanism, which embodies these features, is hereinafter more fully described and its essential characteristics set out in the claims.

In the drawings, Figure 1 is a vertical section through a tandem engine, showing my stufling box in place. Fig. 2 is a cross section on the line 2-2 of Fig. 1. Fig.3 is a fragmentary longitudinal section through the stuffing box.

The drawings show the stuffing box as applied to a tandem engine.

A represents one cylinder of the engine and A the other cylinder. In these cylinders are pistons B B respectivel which are connected by a solid piston ro C.. This piston rod slides through the barrel D of my stufling box which is mounted on the head a of the cylinder A. Set into grooves c in the piston rod are split packing rings E which engage the bore of the member D and with it constitute a stufling box.

The length of the member D is at least as great, and preferably just equal to, the stroke of the engine. Thus the packing rings travel from one end of the bore to the other and being in continuous engagement therewith, preventing leakage. The box needs no more attention than the piston itself.

To allow the convenient removal of the stuffing box without taking the engine entirely apart, I secure it removably to the head a. of the forward cylinder. The for ward end of the stuffing boxseats in an opening in this head, making a tight connection therewith. This connection may be tapered as shown at d and straight as shown at d. The barrel D is rovided with an annular flange d which hes against the outer face of the cylinder head a; the barrel is secured to the head, by means of bolts and nuts F, the bolts passing through the flange into the cylinder head.

With the above described construction, when the rear cylinder head'a is removed and the piston B removed, access is provided to the nuts F, which may thus be removed and the stuffing box taken out. My stuffing box, therefore, requires for its removal no separation of the two cylinders, only part being occasionally removed which would neces-' sarily be removed for attention to the rear piston. I j

In water cooled engines, I make the wall of the stuffing box barrel hollow, the annular passage way (1 thus provided, communicating with the water jacket of one of the cylinders through the cylinder head which carries the stufling box. Thus, as shown in the drawings, the water space (1 of the stuffing box communicates through, lateral ports d with the water space a 1n the cylinder head a, andthis water space communicates with the water jacket a around thecylinder A. By this means the circulation of water through the water jacket of the cylinder causes a circulation through the stufIing box barrel, keeping it cool.

It will be seen that my stufling box, while bein simple in construction and easily applie and removed, has the further advantage of occupying practically no extra space, for it extends simply into the hollow of the Eiston B at the forward stroke of the engine.

xperience has demonstrated that the stuffing box is not only very eflicient in service, but is durable and requires very little attention.

I claim:

1. The combination of a pair of tandem cylinders, a stuffing box removably carried by the intermediate cylinder head, pistons in said cylinders, a rod connecting them and termediate cylinder head, bolts passing through such projection into the cylinder head which carries the barrel, the barrel in advance of such projection being ta ered and occupying a tapered seat in the cy nder head.

2. The combination of a air of tandem cylinders, the head of one 0 said cylinders being composed of an inner and outer member, there being an opening in the outer head-member having a tapering side and an opening in the inner head member with straight sides, and a stuffing box having a flange tapered to fit said tapering seat in the outer cylinder head and a stralght portion ada ted to fit the opening in said inner cylinder ead, and means to hold the stuffing box to the cylinder head.

3. The combination of a pair of tandem cylinders, a stuffing box removably carried by the intermediate cylinder head, pistons in said cylinders, a rod connecting them and passing through the stufling box barrel, the stuffing box having an external projection on the outer side of the intermediate cylinder head, the barrel being tapered in advance of such rojection and occupying a tapered seat in tiie cylinder head, and means coo erating with the projection on the stu ng box for securing the stufiing box to the cylinder head.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
